We just brought our six cats home from the boarding kennel after boarding them for a week. (Yes, it was torture….for me…I worried all week about them and the dogs, even though Ken owns the kennel…)
Anyway, the night we got home all the cats wanted to do was go in and out and in and out the back door. They wouldn’t even leave the porch before wanting back in. I humored them and let each one in and out about six times. Maybe they had to reset some kind of radar after being gone for a week. Or just reassure themselves that the door still works.

Edward seems to think that doors should open on both sides, on the hinge side as well as the regular side–he may expect the hinge side to take him somewhere different, which would make him a philosopher.
